ROOFING CONSTRUCTION.

` aplicaran- 'ie'd :une 16, 1927. serial No. 199,260.

This invention relates more; particularly. to flexible composition shingles of solos/tang'- tially diamond shape having -locking parts or members at their lower corners.

O'ne of the objects of the invention is the improvement oi' such shingles, with a view of simplifying their eoi'istiuction, 'reducing their cost ot' manufacture and producinga smooth roof withoutbulges-.' 'i

'Another object is to socon'struet the shingles that they can'be iiadily adjusted both vertically and 'laterally rin laying them, in order to compensate for inequalities or misalineinent und improve the'ajlipearanee of the roof.

1n the accompanying is a fragmentary top plan View of a roof embodying my invention. 'Figure 2 isa similar View on an enlarged scale, showing drawing, Figure 1 one of the shingles folded back to expose' its locking staples.' Figure 3 is an enlarged horizontal section on line 3 3 Figure 2. Figure 4 is :i transverse section on line 4-4 Figure 1. Figure 5 is a perspective view of one of the locking staples. Figure (i is a View similar to Figure 3 showing a modified form of the staple.

Similar characters or reference indicate corresponding parts throughout their view-S. f

10 indicates the usualro'of boards or sheathing and 11 the starting strip o f roofing material laid along the lower margin of the" gue is formed by cutting al pair vof opposing notches 14.1n the edges of the lower shinglecoriier. This manner of cutting brings the tongue Within shingle and reduces Waste of material to a minimum. Each side corner of the shingle is cut with a notch 15,'the tv vo registering notches of a vpairofadjacent shingles together forming a recess 16 adapted lto receive the tongue 13 ,of `a similar .shingle inwthe overlying course, allowing the tonguewto lie the dimensional lines of the fli`1sli.- With.the face of .the underlying shin- .gles'andproducing asmooth roof over its entire surface.v

. Any appropriate means n'iay be employed to lock the-shingle tongue in the recess 16. The preferred devices consist of a pair oi.

L-shaped staples 17, driven-through the opposingside vcorners of .the pair of underlying shingles and under which the tongue is inserted, as 'best'shosvn .in- Figures 2 and The heads 18 of the staples face each other', preferably Without meeting, but are of suiiicient extent to overlap the margins of the locking tongue aiid reliably hold it in place. These staples thus serve the double purpose of locking the tongue of one shingle and. fastening the opposing side corners o1 the pair of underlying shingles. In applyving` and locking a shingle, its tongue may either be left unfolded, as shown in Figure 2, and .inserted under the heads .of the staples in that'positiori and the shingle body then foldedover the tongue to the final po sition shown in Figure 1; or the tongue iay be tui-ned under the shingle body and `the shingle then moved upward to hook the tongue vunder, its companion staples. In

veitherease, the staples are fully concealed and' protected from the Weather by the shingles. As the tongues lof overlying sli-inglesenter the notches of underlying shingles, the tongues caribe easily inserted vunder the retaining members 18 or 19 without buckling, and being Hush with adjoining shingles, the tongues do not produce bulges in the roof, leaving it flat, smooth and sightly.

The shingle 'tongues and their receiving recesses. 16 are long enough to permit the shingles to `be shifted vertically toa sufricient extent to accurately aline the shingles in the same horizontal roW, and yet retain the tongue with the necessary vsecurity to -Withstand the force of', Windstorms. As

shown in Figures 2 and 3, the recesses are somewhat Wider than the tongues to permit a certain amount of side play of the tongues. This provision 'enables the roofer to adjust the shingles laterally more or less at ornear 'the end of the roof, oir-a valley, to bring the side corners of all the shingles in the saine row against one ,another and produce a sightly, uniformly laid roof. l

The several advantagesl abovedescribed are .obtained by an exceed ngly simple andV inexpensive construction o the shingles and ne l their locking devices andwithout sacriicing ible diamond-shaped diagonally-laid shinglesl the strength and security of the lock.

, The L-shaped ystaples are suitable at the ends of a roof or valley, as Well as atl other places andthey are therefore preferred, but any other appropriatemeans may be substituted for them. For example, ordinary U- shaped staples 19 Wide enough yto bridge the locking tongue and 'penetrate the vadjacent underlying shingles may be used, if desired,

as shown in Figure 6.

' I claimas my invention v 1. In a roofing construction, :1 pair of flexible .diagonally-laid shingles notched in their opposing side edges, forming a recess, a third shingle overlying said pai-r and provided at its lower end with a lockingvtonguel lying in said recess, the latter' being Wider than saidl 'ton' ue, permitting laterall adjustment of the ast-named Shing-le relative tov said first-named pair, andmeans for retaining the tongue 1nv said recess.

Lacasse 2. In a roofing construction, a pair of flexprovided inftheir opposing side corners with *notches, together forming a downwardly-5 opening recess, a third shingle Aoverlying said palr `and provided at its lower end with a locking tongue; lying flush in said recess, and

means for retaining the tongue in said recess. v

v3. In avroofing construction, a pair of flexible diamond-shaped diagonally-laid shingles provided in their opposingside corners lWith registering notches, formmga down-K L-shapcd 4staples wardly-opening recess, Whose stems penetrate the side portions of said pair respectively, while `their heads extend over said notches, and a third shingle provided at its lower corner with a turned.- under locking tongue l ing flush in said recess and engaging un er lthe heads of said staples;
